Upgrade to php 5.1.4 for Zend Studio 5.2

Recently I installed Zend Studio 5.2 in fedora 5.My fedora have php 5.1.4 installed by yum.But Zend Studio 5.2 have php 5.1.1 (I saw this by phpinfo()).So I upgraded php of Zend to 5.1.4 version as guided in this article:http://www.zend.com/....php?kbid=164 iew_only=1

I not edited php.ini in Zend installation folder.But when I pressed F5 to debug, a error message appeared:"Could not debug internally ...". Shocked

I think the different between the environment mentioned in above article with the environment of my fedora is as below:- The above article said that should download and install latestphp from source, then copy the compiled one into ZDE's bin folder and replace the old php file.- But my fedora have php 5.1.4 that not installed from source, itwas installed by yum update.

So could anyone have me to upgrade php of ZDE to php 5.1.4 with

php version that I updated by yum?Please help me. I need your help.Many thanks
